SHEAF-DUMPER FOR HARVESTERS.

SFBJIFICATIODI forming part of Letters Patent No. 339,385x dated April 6, 1886. Application filed November 2G, 1884. Serial No. 148,913. (No model.)

To all whom, it may concern,.-

Be it known that I, JOHN M. DAVIS, a citizen of the United States of America, residing at Staunton, in the county of Macoupin and State of Illinois, have invented Vcertain new and useful Improvements in Sheaf-Dumpers for Harvesters; and l do hereby declare the following to be a full, clear, and exact descrip tion of the invention, suoli as will enable others skilled in the art to which it appertains to malte and use the same, reference being,r had to the accompanying drawings, and to letters or ligures of reference marked thereon, which forni a part of this specilication.

My invention relates to sheatdumpers for harvesters; and it consists in the improvements hereinafter described and set forth.

In the accompanying drawings,which illustrate my invention, Figure l is a perspective view showing,` the same applied toa self-binding harvester. Fig. 2 is an inverted plan view of the carrier and dum per, and Fig. 3 is a detail view.

A represents the frame of a self-bindin,gharvester, which may be ol' any approved pattern. To one of the side beams of said harvester is loosely hinged or pivoted the ends ci' the supporting-beams B B', upon which beams are mounted the sheaf carrier and damper. The beam B extends at rightangles from the beam of the harvester, to which it is pivoted, and at its outer end it is provided with a snpporting-wheel, C, a stub-axle, c, beingv secured to the under side of this beam B. The beam B is attached at its outer end rigidly to the end of the beam B, and diver-ges therefrom, as shown in Fig. 2.

The hinges or connections which attach the ends ci' the beams B B to the frame of the harvester are indicated by the letters b b.

The sheaf-carrying platform D is provided at its forward end with a vertical board, d, and also with a raised side board, d', and a floor, d, which extends a slight distance to the rear of the supporting-beam B. Under the door d are a series of slats, e e, to the front end of which is secured a transverse strip, f. Between each of these slats e e, at the rear of the bar j', are pivoted projecting bars or fingers g, which are secured between the slats e e by a rod, h, so that the same can have an upward play.

The platform or sheaf-carrier is pivoted to the beam B so that the major portion of the carrier will project in front of said beam, and the front portion will rest upon the beam B', and when the same is loaded or empty it is not liable to be tilted accidentally.

By the construction hereinbefore described it will be seen that the sheet-carrying platform may rise and fall with the inequalities of the ground without communicating such motion to the harvester and binder frame; also that the lingers g may rise and fall independent of each other.

The platform D is tilted, when desired, so as to drop the sheaves by the driver oi' the harvester, who depresses a foot-lever located near his seat. the letter t', and has connected thereto a rod, fi', which is attached to the double-crank bar j, pivoted to the frame A. A rod, le, connects the double-crank bar or shaft with a crankarin, k'; which is pivoted to and projects up- Said foot-lever is indicated by wardly from a beam, B, the opposite end of the crank-arm k being rigidly,v attached to the platform D.

The operation of my invention is as follows: The grain is cut and bound into sheaves by the self-binding harvester in the usual man ner, and the sheaves are deposited upon the carrier D at its forward end. .Vhen a sufiicient number of sheaves have been deposited upon this carrier to form a shock or stack, the

foot-lever is depressed to effect the ascent of the rod 2',whioh turns the jointed rodj, moves the bent forward end of the same, and moves the crank-lever k' from a vertical to an inclined position, which causes the platform to be tilted, thus depositing the sheaves upon the ground. As soon as the pressure is taken off the foot-lever, the platform will automatically resume its normal position.

I claim- In combination with a self binding harvester, the beams B B, loosely pivoted to the harvestenframe and provided at their outer ends with a supporting wheel, a platform pivoted to the beam B so that its major portion will project in front of the same, crank-arm k', connectingbar It, double-crank shaftj, and an operating-lever connected to said shaftj, substantially as set forth. v

In testimony whereof I affix my signaturein presence of two witnesses.

Vitnesses: JOHN M. DAVIS.
